Definitions

  • the invention relates to a heat exchanger with at least one tube element through which a heat exchange medium flows and with means for swirling the media flow.
  • Tubular heat exchangers are known for example from DE-OS 30 08 930 and 30 18 978.
  • a tube element has in its interior and over its entire longitudinal extent a partition wall which has a multiplicity of ribs which alternately protrude from the partition wall in opposite directions and bear elastically on the inner wall of the tube.
  • a helical, continuously running strip is accommodated in the tube.
  • the present invention is based on the object of significantly improving the known elements in the characteristics mentioned. In contrast to the known solutions, however, it should also be possible to circulate a plurality of heat exchange media or a plurality of branches of a heat exchange medium in countercurrent through the heat exchanger.
  • Subclaims 2 to 6 relate to preferred embodiments.
  • the sub-claims 7 and 8 relate to preferred applications of the heat exchanger.
  • An inner tube 1 for example made of chromium-nickel steel, carries a wire helix 2 which is loosely wound onto the tube 1 under pretension.
  • the ends of the wire coil 1 can be fixed by spot welding or soldering.
  • the tube 1 with the wire helix 2 is inserted into an outer tube 3.
  • the inner diameter of the outer tube 3 corresponds approximately to the sum of the outer diameter of the inner tube 1 plus the diameter of the wire helix 2.
  • a first media stream 4 is now passed through the annular space between the outer jacket of the inner tube 1 and the inner jacket of the outer tube 3, which is forced into a helical course under the action of the wire coil 2. Since the media flow 4 has to travel a much greater distance than would be the case without the action of the wire helix 2, that is to say the case with a straight line, the heat exchange per unit length of the tube 3 is increased many times over. In addition, the media flow is pressed against the inner jacket of the outer tube 3 under the action of the centrifugal force. In addition, there is a corresponding turbulence.
  • a further media stream 6 can be passed through the inner tube 1.
  • the heat exchanger can now be optimized for any heat exchange problem without changing the manufacturing device, in particular adapted to a predetermined flow resistance.
  • the flow resistance can be increased or decreased within wide limits.
  • FIG. 3 shows that one or more further spiral tubes 7 can be inserted into the inner tube 1. Further media flows can be conducted through the further annular spaces 8 and 9 formed in this way.
  • Fig. 4 shows that a tubular heater 10 can also serve as the inner core of the heat exchanger.
  • the heat exchanger can then serve two different media, e.g. B. air and water to heat.
  • a simple box-like structure 11 can be used to introduce or discharge the media streams.
  • the inner tube 6 is sealed through the box-like structure 11.
  • the media stream 4 which is passed helically through the annular space between the outer jacket of the tube 1 and the inner jacket of the outer tube 3, can be sucked off, for example, through a connecting piece 12 on the box-like structure.
  • a preferred area of application for the heat exchanger is in household clothes dryers.
  • the heated and moist exhaust air is e.g. passed through the annular space between the outer jacket of the inner tube 1 and the inner jacket of the outer tube 3, while the fresh air drawn in flows through the inner tube 1. In this way, the fresh air is preheated.
  • the helix 2 supports the condensation of the water vapor carried along.
